With its unique combination of industry-standard serial-bus (I2C) and contactless RF interfaces, ST’s M24LR EEPROM memory has the ability to communicate with the host system ‘over-the-wire’ or ‘over-the-air.’ Furthermore, the M24LR’s RF interface can convert ambient radio waves emitted by RFID reader-writers and NFC phones or tablets into energy to power its circuits and enable complete battery-free operation.

The M24LR Discovery Kit consists of two boards: an RF transceiver board with a 13.56MHz multi-protocol RFID/NFC transceiver (CR95HF) driven by an STM32 32-bit microcontroller, which powers and communicates wirelessly with a battery-less board that includes ST’s dual-interface EEPROM memory IC (M24LR), an ultra-low-power 8-bit microcontroller (STM8L) and a temperature sensor (STTS75).
